As shown in Fig. 2, the preparation method of above-mentioned flame retardant type one-faced tapes is prepared, specifically,
1) prepare base membrane layer 1: choosing bidirectional stretching polypropylene film, unreel, successively by 150 mesh, 150 mesh, 175 mesh, Base membrane layer 1 is made in the specific net roll one-pass molding of 175 purposes；The net roll surface sets the angle of 120 ° of engraving needles engraving as 45 ° Diamond shape ink cell, the space of a whole page is uniform, and chromium plating again is carved after halftone copper facing；
2) it prepares printing layer 2: one layer of ink being coated in 1 first surface of base membrane layer using rubber roller, is through temperature 75 DEG C of drying tunnel, intake 60%, exhausting amount are 75%, and printing layer 2 is made；The ink is uniformly dispersed, white without obviously leaking And bulky grain agglomerate, glossiness fluctuate within ± 0.3；The ink stirs 30min through 1000~1200r/min, and uses The filtering of 300 mesh filter screens is made；
3) it prepares adhesive layer 3: will include that the sheet EVA resin glue film of Surface Modification of Magnesium Hydroxide by Stearic Acid is adhered to step 2) 2 surface of printing layer made from；Gluing, the sheet EVA are carried out to the sheet EVA resin glue film using precision funny knife It is between 60~70 ° that resin glue film, which requires shore hardness, and institute's gluing is the tackifying resin of the grain of frosted containing magnesium hydroxide, the thickening Resin is rubber, described 1000 μm of magnesium hydroxide frosted grain partial size；
4) flame retardant type one-faced tapes are prepared: step 3) products obtained therefrom is placed in drying, Yu Suoshu adhesive layer in 110 DEG C of drying tunnels 3 surfaces are bonded isolated material, and flame retardant type one-faced tapes are made.
Extension test, anti-flammability test and aging is carried out to flame retardant type one-faced tapes obtained by above three embodiments to survey Examination:
As seen from the above table, the elongation at break of embodiment 1 is greater than 2 product of embodiment, but its anti-flammability is then lower than embodiment 2 Product, this is because the flame retardant amount added in 2 product of embodiment increases, and the increase of frosted grain partial size can drop to a certain extent Low product mechanical strength；In burn-in test, the ageing-resistant performance of 2 product of embodiment is most excellent, and one side fire retardant is largely deposited It is being can absorb a part of heat, 2 high temperature defoaming agent of printing layer also can guarantee the stability of product；On the other hand, base membrane layer 1 selects Material and thickness design are more resistant to aging；And the tensile property of commercially available one side glue, flame retardant property and resistance to old can be seen that by upper table The performance of change is weaker than properties of product disclosed in this invention.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed With.It can be applied to various suitable the field of the invention completely.It for those skilled in the art, can be easily Realize other modification.Therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited In specific details and legend shown and described herein.
